Abstract: A drilling attachment for use with a machine tool that rotates a workpiece in which the drilling apparatus is moved into an operative position to the workpiece by means of the machine tool slide and is rotated with the workpiece so that a drilling member associated with the rotating drilling apparatus is caused to rotate and to enter the workpiece while the same is rotating. The drive means for rotating the drill collet includes an idler gear which allows a greater work area between the rotating portion of said drill attachment and the drill collet on the drill attachment.

Abstract: A cross slide contour forming box tool and base which can be applied to automatic screw machines for contour forming desired contours of desired width on the outside of a workpiece. The contour forming tool is positioned on a transverse slide perpendicular to the drive axis. The transverse slide is driven by a pin and cam groove in the face of a cam so that the contour forming tool is positioned in accordance with the shape of the cam groove. The workpiece is rotated relative to the contour forming tool and the desired contour is formed on the surface of the workpiece. The contour forming tool is carried by a base including a slide and cam which functions to move the box tool parallel to the center line of the workpiece in order to form a desired contour width.

Abstract: A cross slide contour form milling box tool which can be applied to automatic screw machines for contour form milling desired contours on the outside of a workpiece. The contour milling tool is positioned to a transverse slide to the drive axis. The transverse slide is driven by a pin and cam groove in the face of a cam so that the contour form milling tool is positioned in accordance with the shape of the cam groove. The milling cutter is positioned in the transverse slide and rotated by an auxiliary shaft which is driven by gears from the cam shaft using an Oldham coupling to rotate while reciprocating. The workpiece is rotated relative to the contour milling tour and the desired contour is form milled on the surface of the workpiece.

Abstract: A polygon box tool for use with different machine tools by which a cutting and boring operation may be performed simultaneously. The polygon box tool may be used for turning a hexagon shape on the outside diameter of the workpiece while simultaneously turning flats on a smaller diameter in front of the hexagon contour.
